xAI API: what it charges, what it allows, and what it keeps
thecontinuitylayer.com/inference-apis/xai-apixAI's own API for its Grok models.
- 1Yes
Does xAI API publish a per-token price?
Yes, by xAI's own page.
Public docs list per-token prices, e.g. grok-4.7 at $2.00 input / $6.00 output per 1M tokens for prompts under 200k tokens.
Yes means: Per-token prices are on a public page with no sign-in. Partly means only some models are priced in public, or the price sits on a model page rather than the pricing page.
- 2Yes
Does xAI API publish its rate limits?
Yes, by xAI's own page.
The docs publish per-model requests-per-second and tokens-per-minute limits for each spend tier.
Yes means: The docs give request or token numbers for each tier or model. Partly means some numbers, such as a concurrency cap or the top tiers only; no means the numbers are only shown inside a signed-in account.
- 3No
Does xAI API train on your API prompts by default?
No, by xAI's own page.
xAI says it never trains on API inputs or outputs without the customer's explicit permission.
Yes means: Here no is the good answer: the provider's page says what you send its API is not used for training unless you opt in. Yes means it is unless you opt out; partly means it depends on the plan, the tier or the upstream provider.
- 4Yes
Does xAI API say how long it keeps your prompts and outputs?
Yes, by xAI's own page.
Requests and responses are stored encrypted for 30 days for abuse auditing, then deleted, and a team-wide zero-retention setting is available.
Yes means: A stated period, or a statement that nothing is kept by default. Partly means a period for some users or requests but not others.
- 5Not stated
Does xAI API run a public status page?
xAI's pages do not say.
The status page would not open when checked.
Yes means: A public page shows current uptime and past incidents.
